IPL

Tks. I am looking for a manual explaining how mkrom works. This program puts
this signature in the IPL code and another 4 bytes. I have already read this
bytes and only realize that the third one is tha size of the code (in
pages) but I have no idea about the other 3.
Regards.

The fourth byte is a jump instruction, relative to the current position. The
fifth byte indicates to the jmp instruction the offset from the current position
to jump to. The sixth byte is a checksum.
